Schneider Electric (Square D) 9070T75D20 Transformer 208/230/460V PRI 115V SEC

The Schneider Electric (Square D) 9070T75D20 Transformer is a control component used in industrial electrical systems to step down voltage from a 208/230/460V primary supply to a 115V secondary output. Its typically installed inside control panels, air handling units & refrigeration equipment to provide a stable low-voltage source for relays, contactors, thermostats, and control circuits within HVAC systems. By isolating and converting incoming power, it supports better operation of sensitive controls and sequencing components. The transformer is commonly used in system panels where control voltage is required for consistent equipment operation.
